{{Short description|Ligament of the abdomen}} {{Infobox ligament | Name = Pectineal ligament | Latin = ligamentum pectineum | Image = Gray394.png | Caption = The inguinal and lacunar ligaments. | Image2 = | Caption2 = | From = Lacunar ligament | To = Pectineal line }} The '''pectineal ligament''', sometimes known as the '''inguinal ligament of Cooper''', is an extension of the lacunar ligament. It runs on the pectineal line of the pubic bone. The pectineal ligament is the posterior border of the femoral ring.
== Structure == The pectineal ligament connects to the lacunar ligament, and therefore to the inguinal ligament.<ref name=":1">{{Cite journal|last1=Steinke|first1=Hanno|last2=Wiersbicki|first2=Dina|last3=Völker|first3=Anna|last4=Pieroh|first4=Philipp|last5=Kulow|first5=Charlotte|last6=Wolf|first6=Benjamin|last7=Osterhoff|first7=Georg|date=2019|title=The fascial connections of the pectineal ligament|journal=Clinical Anatomy|language=en|volume=32|issue=7|pages=961–969|doi=10.1002/ca.23445|pmid=31381189|issn=1098-2353|doi-access=free}}</ref> It connects to the pectineus muscle on its ventral and superior aspects.<ref name=":1" /> It connects to the rectus abdominis muscle, and the abdominal internal oblique muscle, of the anterior abdominal wall.<ref name=":1" />
